 ## Introduction
 StickySort is a jQuery plugin that creates sticky headers and columns on your tables, complete with the possibility to add a sortable functionality. This plugin was inspired by a recent task at work where I have to create sticky headers to allow users to orient themselves in large tables that, at many instances, fill the full height of the viewport.
